The ThermoMaster Power Chip is designed to be used with a 160 degree or 180 degree PowerStat thermostat. The ThermoMaster Power Chip, used in conjunction with a low-temperature PowerStat thermostat, is the most powerful chip you can run on the street. The ThermoMaster not only provides maximum performance, but it will also help keep the engine cooler in situations of extreme heat such as emergency vehicles, desert driving, competition, etc. Cool air has more air molecules per cubic inch than hot air. An engine running in cool, dense air produces more horsepower and is less likely to detonate than an engine that is taking in hot air.

The Hypertech PowerStat thermostat lowers both the temperature of the incoming air/fuel mixture and the engine coolant temperature. The ThermoMaster Power Chip is programmed to take advantage of this cooler, more powerful air/fuel mixture produced by the Powerstat. All temperature-sensitive functions controlled by the ThermoMaster chip (such as a minimum temperature for torque converter lock-up, closed loop operation, and in some cars, early fan turn-on) are adjusted for a cooler temperature thermostat. The Hypertech PowerStat is specifically designed for use with the Thermomaster Power Chip.

Power Chips for 1981-1995 CarsEarly automotive computers used replaceable PROMs or "chips" to calibrate the Electronic Control Module (ECM) for specific engine, powetrain, and vehicle combinations. Hypertech created the original Power Chips to recalibrate these electronic "brains" for improved performance.

As interest in Power Tuning grew and the variety of OEM systems increased, Hypertech developed innovative products to complement the increasingly complex on-board computer systems. Our engineers designed special carriers and mounts that allowed Hypertech Power Tuning programs to interface with the computer in a wide variety of vehicles.

In 1994, calibration chips were eliminated and the new generation of Electronic Control units (ECU) utilized programmable memory. Hypertech created the Power Programmer to upload Power Tuning programs directly into the ECU. Today Hypertech Power Tuning products span the spectrum of automotive technology. We continue to offer our famous Power Chips for older vehicles, while constantly updating our Max Energy and E-CON Power Programmers for the latest cars and trucks on the market.

Hypertech Power Chips are direct replacements for the stock chips in 1981-1995 GM vehicles. The Power Chip contains the Hypertech Power Tuning data that controls the engine's air/fuel ratio and spark advance for maximum power and performance plus, potential gas mileage improvements. Power Chips can be installed easily, using only hand tools.
